Phytochemical Density

Phytochemical density refers to the concentration and variety of aromatic compounds (terpenes, flavonoids, and other volatile molecules) present in cannabis plant material. Higher phytochemical density typically correlates with more pronounced aromatic expression and complex scent profiles. This trait is influenced by genetics, growing conditions, harvest timing, and post-harvest handling. Breeders and cultivators often assess phytochemical density through organoleptic evaluation and laboratory terpene profiling to understand strain characteristics and consistency across generations.

Breeders working in cannabis genetics frequently select for phytochemical density as a marker of overall plant vigor and secondary metabolite production. Strains with elevated phytochemical density are often prioritized in breeding programs targeting aromatic complexity and genetic stability across multiple phenotypes.
